Definitions

  • This invention relates to quick ice-making units used to shorten the time of making ice in a freezing compartment in current refrigerators and coolers.
  • Ice-obtaining process which is desired to be performed by filling water into an ice container located in the freezing part of the refrigerators, takes usually 30 to 60 minutes depending on the capacity of a refrigerator. It is disadvantageous for the users if this period takes a long time.
  • the system described in the published patent application US 2005076654 has a quick ice-making option
  • a fan and a compressor are used for enabling the quick ice-making option. Air cooled by an evaporator is transferred into a freezer with the aid of a fan, thereby enabling the ice container to be cooled. Air heated as a result of a heat transfer occurred in the freezer section is vented out and re-cooled, and then it is sent back to the freezer section.
  • homogenous cooling of the ice container cannot be achieved in this system.
  • the system described in the published patent application US 2005072166 has a quick ice-making control mechanism.
  • Water is filled into a semicircular ice container and cooled with the aid of an evaporator.
  • a mixer is used to accelerate the heat exchange between water and cold air within the ice container. Ice formation is achieved by the heat transfer occurring with the aid of the mixer.
  • An ice container is provided with a heater at its outer side to remove ice therefrom.
  • an icemaker for making ice in a fresh food compartment of a bottom mount refrigerators comprises a freezer compartment comprising a freezer door, and a fresh food compartment located over the freezer compartment and comprising a fresh food door.
  • the fresh food door comprises an ice dispenser.
  • An ice maker is located in the fresh food compartment, and the ice maker comprises an ice mold, and a thermoelectric device for moving heat from the ice mold.
  • the mold is positioned so that ice from the mold can be dispensed by the ice dispenser in the fresh food door.
  • Said system is especially used for accessing to the ice container, easily, by opening the fresh food door. Therefore it is not related to quick and efficient ice making.
  • an ice making tray is arranged in the ice making chamber, and cold air less than 0°C is supplied to the bottom part of the ice making tray to make ice in the ice making tray.
  • An opening is formed in a part, positioned above the ice making tray, of a partition, and a cover is provided for closing the opening.
  • the cover is formed with a flow part for allowing the flow of cold air from the vegetable chamber, and a blower fan for leading the cold air from the vegetable chamber, to the water surface of the ice making tray is arranged between the cover and the ice making tray.
  • the cold air from the vegetable chamber i.e., the cold air with a temperature exceeding 0°C
  • the cold air with a temperature exceeding 0°C is thereby led to the water surface of the ice making tray, which is made energy-saving type compared to constitution of obtaining warm air using an electric heater. Therefore it is not related to quick and efficient ice making. It is especially used for cold air circulation between vegetable chamber and ice making chamber.
  • quick ice-making units of this invention can be used.
  • An ice container made of a material having high thermal conductivity is filled with water and placed onto ice-making units of the invention provided with insulated outer surfaces, which are located in the freezing compartment.
  • High-flow cold air fluxes are achieved in the ice-making units of the invention equipped with thermoelectric cooler and/or cold air blower, thereby water in the ice container with high thermal conductivity is solidified quickly.
  • the aim of this invention is to provide ice-making units equipped with thermoelectric cooler and/or cold air blower in order to quickly cool water in the ice container having high thermal conductivity and transform it into ice using forced air circulation in a freezing compartment.
  • Another aim of the invention is to enable these units to be utilized in currently used refrigerators or coolers.
  • the invention is quick ice-making units in a freezing compartment which use a cooling technique based on directing ambient air forcibly by a fan (15) - motor (16) mechanism located in a freezing compartment into the compartment of a cooling element (17) such as an evaporator and cooling this air while passing over the cooling element (17) and re-transferring it into the freezing compartment (1) or the ice chamber (2, 12) from air blowers.

Cool air flows around these compartments and reaches the upper side of the ice container (3) and the lower part of the separator (4) from said holes (9), thereby advancing towards the front passage (11). While the temperature of air advancing towards the front passage (11) increases somewhat due to heat transfer between the ice container (3) and water therein, the temperature of water decreases as mentioned earlier.
